DISP-12. RACIAL DISPARITY IN LENGTH OF STAY FOLLOWING CRANIOTOMY FOR PRIMARY BRAIN GLIOMA

Abstract

Abstract Introduction The racial disparities of opportunity to receive the appropriate surgical intervention and insurance coverage for adjuvant care may result in surgical outcome and survival disparities among different races. Length of stay (LOS) is an important quality metric measure for determining the distribution of medical resources and their consumption. This study aims to provide a perspective on racial disparities in the overall length of stay and complications for patients undergoing craniotomy for primary brain glioma. METHODS The authors performed a retrospective chart review of all patients who underwent craniotomies for resection of primary brain tumors at the Moffitt Cancer Center from 2004-2018. Patients age, race, tumor type, comorbidities, length of stay and complications were reviewed. RESULTS A total of 701 patients underwent craniotomies for primary brain glioma, but 66 were excluded due to insufficient follow-up or incomplete records. The racial categories include Caucasians, African American, Asian, Hispanic, and other. Due to the prevalence of Caucasians, the minorities groups were pooled as non-Caucasians. Both cohorts were similar in baseline comorbidities, KPS, tumor characteristics, and surgical factors. Mean LOS remained lower for Caucasians versus non-Caucasians (3.6 vs. 5.5 d). The differences in LOS remain among different tumor types, including GBM (4 vs. 6.7 d), anaplastic astrocytoma (2 vs. 4.4 d), and oligodendroglioma (2.3 vs. 3.7 d). Interestingly, among astrocytoma, Caucasians had a longer LOS (3 vs 1.2 d). CONCLUSION Our results highlight disparate treatment patterns that reflect in LOS among patients undergoing craniotomies for primary brain gliomas. These findings warrant further investigation regarding current health-care practices and policies.
